Lua file: read unexpected behavior

I am a complete newbie to Lua and I came across a problem that I don't understand.

So I am trying to open a file, read the data and store it in another file with a different name.

Here is the code

local infile = io.open(folder..'/'..f, "r")
local instr = infile:read("*all")
infile:close()

local outfile = io.open(folder..'/'..newName, "w")
outfile:write(instr)
outfile:close()

As a result, I get 288Kb original file and 2Kb Destruction file

So, since I'm new to Lua, the fact that the problem is in infile:read

is a wild guess for me, but the way I see it, it infile:read

's either outfile:write

.

UPD: The content is completely arbitrary, which implies the presence of special characters.

Thank you in advance,

Hello!

I did this by opening the input and output files in binary, adding a flag b

to the call io.open

. So I have the code



        local infile = io.open(folder..'/'..f, "rb")
        local instr = infile:read("*all")
        Log(instr)
        infile:close()

        local outfile = io.open(folder..'/'..newName, "wb")
        outfile:write(instr)
        outfile:close()
